It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0039] In the following description, certain specific details are set forth for the purpose of illustrating the various disclosed embodiments to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with the present application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0041] In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used for description, but the words "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as restrictive terms.

[0042] Figure 1 FIG. 1 is a perspective exploded view of a lens driving mechanism 100 according to an embodiment of the present invention. Figure 1As shown, a lens driving mechanism 100 according to an embodiment of the present invention comprises a housing 10, an upper spring 20, a magnet group 30, a carrier 40, a lower spring 50, a base 60, and a base embedded metal sheet 70. The base embedded metal sheet 70 is arranged in the base 60, the magnet group 30 is fixedly mounted on the housing 10 or the base 60, the carrier 40 is used to install the lens and is provided with a coil corresponding to the magnet group 30, the upper spring 20 movably connects the upper surface of the carrier 40 with the housing 10, and the lower spring 50 movably connects the lower surface of the carrier 40 with the base 60. The housing 10 cooperates with the base 60 and installs the upper spring 20, the magnet group 30, the carrier 40, and the lower spring 50 in a space defined by the housing 10 and the base 60. When the coil in the carrier 40 is energized, it interacts with the magnetic field formed by the magnet group 30, drives the carrier 30 and then drives the lens installed in the carrier 30, thereby realizing functions such as autofocus or optical image stabilization.

[0043] Since the carrier 30 may collide with the inner wall or the base of the shell 10 during operation, fine particles will be generated when colliding with the inner wall of the shell 10. These particles will interfere with the imaging of the lens and affect the effect. Therefore, the present invention avoids this situation by adding an elastomer to the shell 10 and / or the base 60, and / or the carrier 40 to prevent the carrier 40 from directly contacting the shell 10 or the base 40, thereby achieving a higher quality imaging effect.

[0044] The housing 10 , the carrier 40 and the base 60 according to different embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Figure 2 is a three-dimensional diagram of the housing 10, Figure 3 is a bottom view of the housing 10, Figure 4 1 is a top view of the housing 10. Figure 2-4 As shown, the housing 10 includes a housing top 11 and a housing side 12, a top opening 13 is formed in the middle of the housing top 11, and the housing side 12 is integrally formed with the housing top 11 and extends toward the base substantially perpendicular to the housing top 11. The housing top 11 has a rectangular structure as a whole, and each side of the rectangular structure is connected to a housing side 12, forming a housing top 11 and four housing side 12 as a whole.

[0046] The four corners of the housing top 11 sink toward the base 60 to form a sinking portion 14, and an elastic body mounting portion 15 is formed between every two sinking portions 14, and the elastic body mounting portion 15 and the sinking portion 14 are arranged around the top opening 13. The elastic body mounting portion 15 is provided with a first elastic body 90. Among them, the housing top 11 has a lower surface 112 facing the base 40 and an upper surface 111 opposite to the lower surface 112. The first elastic body 90 is arranged on the lower surface 112 of the housing top 11, specifically the lower surface of the elastic body mounting portion 15, to prevent the carrier 40 from directly contacting the lower surface 112 of the top of the housing 10 during movement.

[0047] exist Figure 2-4 In the illustrated embodiment, each elastic body mounting portion 15 is provided with a first elastic body 90, so that four first elastic bodies 90 are provided on the lower surface 112 of the top portion 11 of the housing 10, that is, a first elastic body 90 is provided between every two sinking portions 14. It should be noted that those skilled in the art can understand that each elastic body mounting portion 15 can also be provided with a plurality of first elastic bodies.

[0048] Figure 5-6 1 and 10 are respectively a bottom view and a top view of the housing 10 without the first elastic body 90 installed. Figure 2-6 , each elastic body mounting portion 15 of the housing 10 is provided with an elastic body mounting hole 151, the first elastic body 90 includes a main body 91 and a connecting portion 92, the connecting portion 92 is arranged in the elastic body mounting hole 151, and the main body 91 is arranged on the second surface 112 of the top 11. By adding the connecting portion 92 and the elastic body mounting hole 151, the first elastic body 90 can be fixed to the bottom of the elastic body mounting portion 15. Specifically, each elastic body mounting hole 151 extends from the upper surface 111 of the housing top 11 to the lower surface 112 of the housing top 11 and forms a first opening 113 on the upper surface 111 and a second opening 114 on the lower surface 112. The elastic body mounting hole 151 has an inclined inner wall, so that the first opening 113 of the elastic body mounting hole 151 close to the upper surface 111 is larger, and the second opening 114 close to the lower surface 112 is smaller.

[0049] Reference Figure 2-3, the width of the main body 91 of each first elastic body 90 is equal to the width of the elastic body mounting portion 15, that is, the main body 91 of the first elastic body 90 covers the lower surface of the elastic body mounting portion 15 along the width direction of the elastic body mounting portion 15. Preferably, the outer side of the main body 91 of the first elastic body 90 has a shape that matches the periphery of the top opening 13 of the housing 10 and is aligned with the periphery of the top opening 13, so that the carrier 40 will only contact the main body 91 of the first elastic body 90 during movement, effectively avoiding the collision between the carrier 40 and the housing 10. In addition, in order to effectively prevent the collision between the carrier 40 and the top lower surface 112 of the housing 10, the thickness of the main body 91 of the first elastic body 90 is preferably greater than a certain value, for example, greater than or equal to the thickness of the lower housing 10.

[0050] The following describes a method for setting the first elastomer 90 on the housing 10 by injection molding. The elastomer mounting hole 151 on the housing 10 is also referred to as an injection hole. By injecting an elastomer profile from the upper surface 111 of the top 11 of the housing 10 into the elastomer mounting hole 151, a main body 91 of the first elastomer 90 is formed on the lower surface 112 of the top 11 of the housing 10 and a connecting portion 92 of the first elastomer 91 is formed in the elastomer mounting hole 151. The first elastomer 90 can be made of, for example, thermoplastic polyurethane elastomer rubber (TPU), and the molten TPU is injected through the first opening 131 of the elastomer mounting hole 151 and flows into the lower surface 112 of the housing 10 and forms the main body 91 of the first elastomer 90 on the elastomer mounting portion 15.

[0051] Combine the following Figure 7-9 The base of the present invention is described. Figure 7 is a top view of the metal sheet 70 embedded in the base, Figure 8 is a bottom view of the metal sheet 70 embedded in the base, Fig. 9 is a top view of the base 60. Figure 7-9 As shown, the base 60 includes a base body 61 and a base embedded metal sheet 70 disposed in the base body 61. The base embedded metal sheet 70 is generally annular and has a metal sheet upper surface 71 facing the lower surface of the carrier and a metal sheet lower surface 72 opposite to the metal sheet upper surface 71. The metal sheet upper surface 71 is provided with a second elastic body 80 to prevent the carrier 40 from directly contacting the base 60 during movement.

[0052] In one embodiment, the base embedded metal sheet 70 is provided with a plurality of second elastic body mounting holes 73, and the plurality of second elastic body mounting holes 73 extend from the upper surface 71 of the base embedded metal sheet 70 to the lower surface 72. Specifically, an opening 74 is formed in the middle of the base embedded metal sheet 70, and a plurality of second elastic body mounting parts 75 are arranged around the opening 74 in the middle, and the plurality of second elastic body mounting parts 75 are preferably symmetrically arranged on the annular base embedded metal sheet 70 and arranged opposite to each other in pairs. Two adjacent second elastic body mounting parts 75 are connected by a connecting part 76. The width of the second elastic body mounting part 75 is greater than the width of the connecting part 76 to facilitate the installation of the second elastic body 80. Two second elastic body mounting holes 73 are provided on each second elastic body mounting part 75. Correspondingly, the second elastic body 80 includes an integrally formed main body part 81 and a fixing part 82, and the fixing part 82 is integrally extended from the surface of the main body part 81 and is used to cooperate with the second elastic body mounting hole 73 on the base embedded metal sheet 70. During installation, the fixing portion 82 is inserted into the second elastic body mounting hole 73, and the main body 81 is arranged on the second elastic body mounting portion 75. The fixing portion 82 can be a connecting column, for example, two connecting columns are integrally extended from the surface of the main body 81, that is, one second elastic body 80 includes one main body 81 and two connecting columns 82, and correspondingly, two second elastic body mounting holes 73 are set on each second elastic body mounting portion 75, and the two connecting columns extend into the two second elastic body mounting holes 73 for fixing.

[0053] In one embodiment, the second elastomer mounting hole 73 has an inclined inner surface, so that the radius of the second elastomer mounting hole 73 close to the upper surface 71 of the metal sheet is large, and the radius of the part close to the lower surface 72 of the metal sheet is small, thereby facilitating the fixing part 82 of the second elastomer 80 to be installed in the second elastomer mounting hole 73.

[0054] Reference Fig. 9 The base 60 is provided with an opening 62 at a location corresponding to the main body 81 of the second elastic body 80, so that when the base embedded metal sheet 70 is installed in the base body 61, the main body 81 of the second elastic body 80 installed on the base embedded metal sheet 70 protrudes from the upper surface of the base 60. When the carrier 40 moves toward the base 60, it first contacts the second elastic body 80. Since the second elastic body 80 has a certain thickness, it can effectively prevent the carrier 40 from directly hitting the base 60, effectively preventing the damage of the carrier 40 and preventing the small particles generated during the collision from dirtying the lens and affecting the imaging effect.

[0055] Combine the following Figure 10-13 The carrier 40 and the manufacturing method thereof according to an embodiment of the present invention are described. FIG10 is a top view of the carrier 40 according to an embodiment of the present invention. Fig.11FIG. 4 is a bottom view of a carrier 40 according to an embodiment of the present invention. Figure 10-11 As shown, a lens mounting hole 41 for mounting a lens is provided in the middle of the carrier 40, and a main body 42 of the carrier is formed around the lens mounting hole 41 and has a carrier upper surface 421 and a carrier lower surface 422. The carrier upper surface 421 is provided with a plurality of upper spring connecting parts 423, and the carrier lower surface 422 is provided with a plurality of lower spring connecting parts 424. The carrier upper surface 421 and the carrier lower surface 422 are further provided with a third elastic body 43 to prevent the carrier upper surface 421 from directly contacting the inner surface of the housing 10 and to prevent the carrier lower surface 422 from directly contacting the upper surface of the base 60. It should be noted that, although the carrier 40 described here is provided with a third elastomer on both the upper surface and the lower surface of the carrier, those skilled in the art will understand that, as long as the third elastomer is provided on one of the upper surface and the lower surface of the carrier, the technical effect of the present invention can be achieved to a certain extent. For example, providing the third elastomer only on the upper surface 421 of the carrier can prevent the carrier 40 from colliding with the inner surface of the outer shell, and providing the third elastomer only on the lower surface 422 of the carrier can prevent the carrier 40 from colliding with the upper surface of the base.

[0056] In one embodiment, the carrier 40 is provided with an elastic body mounting hole 44, the elastic body mounting hole 44 extends from the carrier upper surface 421 to the carrier lower surface 422 and forms an upper opening on the carrier upper surface 421 and a lower opening on the carrier lower surface 422, and the third elastic body 43 is disposed in the elastic body mounting hole 44 and protrudes upward from the carrier upper surface 421 and protrudes downward from the carrier lower surface 422, that is, the elastic body disposed on the carrier upper surface 421 and the elastic body disposed on the carrier lower surface 422 are two ends of the same elastic body. However, it can be understood by those skilled in the art that the elastic body disposed on the carrier upper surface 421 and the elastic body disposed on the carrier lower surface 422 can also be independent of each other, that is, the elastic body disposed on the carrier upper surface 421 and the elastic body disposed on the carrier lower surface 422 are different elastic bodies.

[0057] Reference Figure 10-11 The upper opening of the elastic body mounting hole 43 is arranged at the upper spring piece mounting portion and avoids the contact position between the upper spring piece and the upper surface of the carrier, and the lower opening of the elastic body mounting hole 43 is arranged at the lower spring piece mounting portion and avoids the contact position between the lower spring piece and the lower surface of the carrier. Therefore, the connection between the upper spring piece and the lower spring piece will not be affected by the provision of the third elastic body. In one embodiment, a plurality of elastic body mounting holes 43 are evenly arranged around the lens mounting hole 41 of the carrier 40, thereby effectively preventing the collision between the carrier 40 and the housing and the base, while reducing the amount of the elastic body.

[0058] In one embodiment, the upper spring mounting portion 423 is formed by protruding a certain distance from the upper surface 421 of the carrier 40, a sinking portion 425 is formed between two adjacent upper spring mounting portions, and each upper spring mounting portion 423 is provided with an elastic body mounting hole 43. Similarly, the lower spring mounting portion 424 is also formed by protruding a certain distance from the lower surface 422 of the carrier 40, a sinking portion 426 is formed between two adjacent lower spring mounting portions, and each lower spring mounting portion 424 is provided with an elastic body mounting hole 43.

[0059] In one embodiment, a side hole (not shown) is formed near the upper surface 421 of the carrier of the elastomer mounting hole 43 , the side hole is connected to the elastomer mounting hole 43 , and the third elastomer is filled in the elastomer mounting hole 43 and the side hole.

[0060] Reference Fig.11 In one embodiment, the upper end of the elastic body 44 is provided with an arc-shaped protruding block 441, the side hole has an arc-shaped periphery, and the arc-shaped protruding block 441 is arranged in the side hole (not shown) of the carrier 40. During the manufacturing process of the third elastic body 43, the side hole can be used as an injection hole for the third elastic body.

[0061] Combine the following Figure 12-13 A method for manufacturing a carrier 40 according to an embodiment of the present invention is introduced. Fig.12 is a top view of a third elastomer assembly formed by positioning a plurality of third elastomers through a material strip according to an embodiment of the present invention, Fig.13 is a top view of the carrier with the third elastomer assembly installed, such as Figure 12-13 As shown, in this embodiment, the carrier 40 is formed by injection molding, the third elastomer 44 is formed before the carrier 40 is formed by injection molding and is arranged in the carrier injection molding mold, and the third elastomer 44 is fixed in the elastomer mounting hole 43 of the carrier 40 after the carrier 40 is formed.

[0062] Reference Fig.12 In one embodiment, a plurality of third elastic bodies 44 are positioned by the material strip 45, and the third elastic bodies 44 and part of the material strip remain in the carrier 40 after the carrier 40 is formed. For example, the carrier 40 includes four third elastic bodies 44, and the material strip 45 has a rectangular frame structure, and the four corners of the rectangular frame are connected to the third elastic bodies 44 through the connecting portion 451 and position the third elastic bodies 44. In one embodiment, a bending portion 452 is provided at the front end of the connecting portion 451, and the bending portion 452 is provided with an annular ring 453, and the annular ring 453 is arranged around the third elastic body 44, and the outer diameter of the third elastic body 44 matches the inner diameter of the annular ring 453, and the protruding block 441 of the third elastic body 44 is located above the annular ring 453.

[0063] Specifically, according to an embodiment of the present invention, the method for manufacturing the carrier 40 may include the following steps:

[0067] It should be noted that the elastomers described above, including the first elastomer, the second elastomer and the third elastomer, can be made of elastic materials. However, preferably, the first elastomer, the second elastomer and the third elastomer can be made of thermoplastic polyurethane elastomer rubber (TPU).

[0068] It should be noted that the above specifically introduces the housing, base and carrier of the lens drive mechanism of different embodiments of the present invention. These housings, bases and carriers may belong to the same lens drive mechanism or to different lens drive mechanisms. That is to say, the housing of the present invention can be used for other lens drive mechanisms, and the lens drive mechanism does not need to have the base and carrier described in the present invention.
